It's not their job to share content': a case study of the role of senior students in adapting teaching materials as open educational resources at the University of Cape Town [PDF]

, 2013
Inspired by the Massachusetts Institute of Technology's landmark decision to make its teaching and learning materials freely available to the public as OpenCourseWare (OCW), many other higher education institutions have followed suit sharing resources ...

Hybrid Metal–Organic Framework‐Derived Dual Active Site Catalysts Enabling Surface‐Enriched Cathode and Modified Zinc Anode for Long‐Life Zinc–Air Batteries

Advanced Science, EarlyView.
This work demonstrates the implementation of MOF‐assisted anode and cathode materials for prolonged cycling of zinc‐air batteries with strong redox capability and structural stability. ABSTRACT The surface modification of zinc anodes and the development of effective cathode dual‐functional oxygen electrocatalysts remain of paramount interest for ...

Praseodymium‐Modulated NiFe Layered Double Hydroxide with Enhanced Oxygen Evolution Activity and Extended Durability [PDF]

Advanced science
Pr doping of NiFe‐LDH simultaneously tunes Ni 3d electronics and mesopore architecture. The optimized Ni2Fe0.88Pr0.12‐LDH switches the OER rate‐determining step, delivers 407 mV at 500 mA cm−2, and sustains 2190 h in half‐cell tests. An AEM electrolyzer with this anode operates over 1000 h at industrial current density, offering a durable rare‐earth ...

Explaining the Rent-OER Inflation Divergence, 1999-2006 [PDF]

Between 1999 and 2006, there were two episodes during which inflation in the Rent index in the CPI diverged markedly from inflation in the index for Owner’s Equivalent Rent (OER); early in 2007, these series began to diverge again.

Deciphering Structure‐Bubble‐Mass Transfer Relationships in Water Electrolysis Through Electrode Morphology Regulation

Advanced Science, EarlyView.
Electrode morphology is shown to govern oxygen‐bubble dynamics and interfacial mass transfer during water electrolysis. Positive‐curvature nanoneedles promote rapid release of small bubbles, sustain electrolyte renewal, and minimize mass‐transport losses, whereas flat and concave architectures increasingly retain bubbles.

An OER framework, heuristic and lens: Tools for understanding lecturers’ adoption of OER

Open Praxis, 2017
This paper examines three new tools – a framework, an heuristic and a lens – for analysing lecturers’ adoption of OER in higher educational settings. Emerging from research conducted at the universities of Cape Town (UCT), Fort Hare (UFH) and South Africa (UNISA) on why lecturers adopt – or do not adopt – OER, these tools enable greater analytical ...

Nickelferrite on Pnictogen Functionalized Carbon Nanohorns. Bifunctional ORR and OER Catalysts in Rechargeable Zinc‐Air Batteries

Advanced Science, EarlyView.
A systematic study on the performance of N,P‐doped NiFe2O4@CNH bi‐functional hybrid electrocatalysts for rechargeable zinc‐air batteries is presented. The importance of P, N‐doping and the intimate tethering of nickel‐ferrite nanocubes on the carbon nano‐horn (CNH) surface which are well dispersed on the surface of N,P doped CNHs.

Mary Lou Forward-International OER Initiatives: OER Community Conversations

, 2010
OER is a wide term, encompassing different concepts. Many people appreciated Steve Carson's description of different roles that OER can fill as summarized by Thomas Pfeffer: OER as a substitute, OER as a reusable resource, OER as transparency, and OER ...
